Title: Process for doping crystals of wide band gap semiconductors
Inventor: NEUMARK GERTRUDE F
IPC: C30B29/48
Filed: 1989-08-14
Granted: 1993-12-28
Abstract: ABSTRACT OF THE DISCLOSURE Non-equilibrium impurity incorporation is used to dope hard-to-dope crystals of wide band gap semicon-ductors, such as zinc selenide and zinc telluride.  This involves incorporating into the crystal a compensating pair of primary and secondary dopants, thereby to increase the solubility of either dopant alone in the crystal. Thereafter, the secondary more mobile dopant is removed preferentially, leaving the primary dopant predominant. This technique is used to dope zinc selenide p-type by the use of nitrogen as the primary dopant and lithium as the secondary dopant.  Alternatively, the technique may use nitrogen as the primary dopant and the hydrogen as the secondary dopant to obtain low resistivity p-type zinc selenide.

Abstract: ABSTRACT Aqueous, clay-based drilling mud compositions are improved with respect to waterloss control by the addition of a hydrolyzed copolymer of acrylamide and an N-vinylamide.  The copolymer, which is effective over a broad range of molecular weights, contains at least 5 mol percent of the N-vinylamide monomer moiety of which at least 5 mol percent is hydrolyzed to vinylamide units. Well drilling is improved by circulating through the bore hole a drilling mud containing this waterloss control additive.
